Load Calculation Support

Load calculation support turns a complete structural brief into a practical grating pre-selection. You provide the clear span, load cases, contact areas, supports and governing criteria; we return a recommended bearing-bar direction and section range, with the calculation basis where the agreed scope requires it.

Inputs required before a load review

The review starts only when the load path is clear. Provide the clear support span measured in the bearing-bar direction, the support-seat arrangement, every applicable load case and the project deflection or safety criteria. A platform-area load alone is not enough when wheels, legs, pallets or equipment concentrate force over a smaller contact area.

  • Clear span and bearing-bar direction
  • Uniform, concentrated and wheel loads with contact areas
  • Support width, continuity, cantilevers and unusual boundary conditions
  • Material, corrosion allowance and serrated or plain surface
  • Applicable project standard, safety factor and deflection limit

What the review can return

The output is a project-specific pre-selection: suitable bearing-bar section or options, the assumed spacing and bearing direction, and the governing load case identified from the supplied information. Where calculation notes form part of the agreed scope, the method and assumptions can be stated for review.

Reference tables remain useful for early comparison. The related Load Tables page gives the data and its limitations; this service page explains the workflow for applying project inputs. The two are intentionally separate.

  • Recommended section or a short list of workable options
  • Assumptions and missing inputs that still require confirmation
  • Reference to the governing load case and deflection criterion
  • Questions or drawing changes needed before quotation or production

Service boundary

The result depends on the accuracy and completeness of the information supplied. Wheel impact, fatigue, seismic effects, fire design, unusual restraint, supporting steel and local regulations remain within the responsible project engineer’s scope unless a separate written scope states otherwise.

Final structural approval belongs to the owner or their qualified engineer. Production starts only from the approved specification and drawings; no draft website statement replaces project calculations, design approval or governing codes.

Process

How It Works

  1. Send the structural brief

    Provide span, loads, contact areas, supports, material, environment and governing criteria.

  2. Input check

    Missing or conflicting values are listed before a section is proposed.

  3. Pre-selection

    Bearing direction, spacing and a practical section range are compared against the stated cases.

  4. Calculation review

    The governing case, assumptions and deflection criterion are documented to the agreed level.

  5. Project confirmation

    The owner or responsible engineer reviews the recommendation before quotation and production.

Checklist

What to Prepare

  • Layout drawing with supports and bearing-bar direction
  • Clear span for every panel zone
  • Uniform loads with units
  • Point loads with loaded area and position
  • Wheel loads with contact area, spacing, frequency and impact criteria
  • Material, surface, finish and corrosion allowance
  • Required standard, safety factor and deflection limit
  • Any cantilever, continuity, vibration or dynamic condition

FAQ

Load Calculation Support FAQs

Can I send only the total vehicle weight?
No. Wheel load, tire or contact area, axle or wheel spacing, traffic frequency, impact criteria, span and supports are needed for a useful review.
How is this different from the load tables page?
The load tables provide reference data and limitations. This service applies your actual span, loads, supports and criteria to a project-specific pre-selection.
Does the recommendation replace the project structural engineer?
No. It supports product selection from the information provided. Final design acceptance and code compliance remain with the owner or responsible qualified engineer unless a separate written scope states otherwise.
